Question

given the mean of a data set is 56 and the standard deviation is 10, where will about 68% of the data lie? 1 to 10 46 to 66 10 to 56

Explanation:

Step1: Recall the empirical rule

In a normal - distribution, about 68% of the data lies within 1 standard deviation of the mean.

Step2: Calculate the lower and upper bounds

The lower bound is the mean minus the standard deviation: $56 - 10=46$. The upper bound is the mean plus the standard deviation: $56 + 10 = 66$.

Answer:

B. 46 to 66
